KAZIMIER DOMBKOWSKI, OF AMSTERDAM, NEW YORK.

LIFE-BOAT.

Application filed June 15, 1914., semi No. 845,123.

To all whom it may concern Be it known that I, KAZIMIER DUMBKOW- SKI, a subyect of the Emperor ofGermany,

residing at Amsterdam, in the county of.

Montgomery and State of New York, have invented certain new and useful Improvements in Life-Boats, of which the follow-.

With the above general objects in: view and others that will appear as the nature of the invention is better understood, the same consists in the novel construction, com bination and arrangement of parts to be hereinafter more fully described and then claimed, reference being had to the accompanying drawings which show the preferred embodiment of the present invention, by like characters designating corresponding parts throughout the several views and wherein Figure 1 is a side elevational view of the device, partly in section. Fig. 2 is a cross sectional view of the same taken on line IIII of Fig. 1. Fig. 3 is an enlarged detail side elevational view of the mechanism for locking the casing. Fig. 4: is an enlarged top plan view, partly in section and broken away, of a portion of the peripheral deck and casing, and Fig. 5 is an enlarged detail sectional view of a portion of the casing, strap and friction roller. 1

Briefly described, the invention embodies a casing surrounded by a plurality of transverse straps, such straps carrying anti-friction rollers on their inner faces that are adapted to engage the casing, while a weighted keel is suspended from the lower ends of the straps. Suitable projections are carried by each end of the casing and journaled on said projections is a peripheral deck, such deck adapted to completely surround the casing and forming an endless passageway and connected at suitable points Specification of Letters Patent.

'ingmeans such as indicated at 13.

to the straps,whereby the same is caused to always assume a horizontal posltlon. A carriage is suspended within the casingand is 1 adapted to always assume a horizontal position. Peripheral teeth are formed on portions of the casing are inclosed by the strap members and are adapted to be engaged by arms controlled by levers carried by the deck so that rotary motion of the casing may be stopped and the device held in a substantially rigid position for persons to either enter the same or make their exit.

Referring more in detail to the accom panying drawings, the reference numeral 10 designates a casing of suitable shape as shown in Fignl with windows 11 and entrance doors 12,. such doors being held in closed orlocked position by suitable fasten- Each end-of the casing 10 is provided with a lug or. projection 141, and journaled on each pro jection is the peripheral decklfi. The projectionslt are provided with sockets or recesses opening into the casing 10 and are adapted to receive the trunnion pins 16 can ried by eachend of the passenger carriage 17, such carriage being of a shape and weight to always assume a horizontal position regardless of the position of the easing 10. v

The peripheral deck 15 has the bracket 18 at each end thereof journaled on the casing projections 15k and extends in .an endless path around :jthe casing, as clearly shown in Fig. 1,the platform 19 of the deck being of slat construction as shown in Fig. 4:. Each side of the deck 15 is provided with an inner and outer wall 20, the outer wall being preferably inclined as shown in Fig' 1 so that waves moving against the same may be deflectedywhile the inner wall of the deck is cut away at points opposite the casing doors 12. 1 1

The casing 10 is adapted to be revolubly supported in transversely arranged straps 21 having one side of the inner face thereof cut away as at 22, as shown in Fig. 5, to provide clearance for the peripheral teeth 23 carried by the casing 10 and having journaled therein on the pins 24 the friction rollers 25 that are adapted to engage the said casing. Any suitable number of these straps may be provided and connected to the lower ends of the same as at 26 is a keel 27 of suitable weight and shape, but preferably as shown in Figs. 1 and 2. In order to hold the peripheral deck 15 in a normally horizontal position, the same is connected at the points 28 to the straps 21.

Means are provided to arrest rotary move ment of the casing 10 Within the straps 21 and'consists of a support 29 carrying a rack segment 30 mounted on the slatted floor 19 of the peripheral deck, preferably at each side of the casing 10 as shown in Fig. 2. Pivotally mounted in the bracket 29 as at 31 is the controlling lever 32 that carries the arms 33, such arms being guided as at 34 and suitably bent as at 35 to be brought into position as shown by Fig. 4 to engage the peripheral casing teeth 23. The arms 33 are connected at opposite sides of the pivot point 31 so that movement of the controlling lever 32 will simultaneously release the said arms from the casing teeth and also simultaneously move the same into engagement with the said teeth.

In operation, the arms 33 are normallv held in retracted position and free of the casing teeth 23 sov that the casing may be freely revolved within the straps 21, the friction being reduced by the roller bearings 25 carried by the said straps. When it is desired to arrest rotary movement ofthe casing 10 to bring the doors 12 into position adjacent the peripheral deck 15, for the entrance or exit of passengers, after such position has been obtained, the controlling lever 32 when suitably shifted will move the ends 35 of the arms 33 into engagement with the peripheral teeth 23 on the casing and be retained in such position by the lever lock engaging the rack segment 30. In such position, the lock 13 on the door 12 may be released and the door opened for the entrance or exit of passengers.

While I have shown and described the preferred embodiment of my invention, I do not wish to be confined to the exact details of construction shown, as various forms, modifications and arrangement of the parts as shown may be had without departing from the spirit and scope of the appended claims.

What I claim as new is 1. In a device of the class described, a

casing comprising windows and entrance doors, a carriage suspended within said casing, straps surrounding said casing, a weighted keel secured to the lower ends of said straps, friction rollers carried by the straps and engaging the casing, and means adapted to be brought into engagement with the casing to arrest movement thereof.

2. In a device of the class described, a casing, a carriage suspended within the casing, a peripheral deck surrounding the easing, transverse straps surrounding the casing and connected to the deck, a keel secured to the lower ends of the straps, roller bearings interposed between the casing and straps, and means carried by the deck adapted to engage the casing to arrest rotary movement thereof.

3. In a device of the class described, a casing, a carriage suspended within the same, means in which the casing is adapted to revolve, an endless peripheral deck carried by the said means, peripheral teeth at spaced points on the casing, and means carried by said deck adapted to be brought into engagement with said teeth to arrest movement of said casing.

4t. In a device of the class described, a casing, peripheral teeth formed on portions of said casing, straps surrounding the easing and inclosing said teeth, a peripheral deck secured to said straps, levers pivotally mounted on the deck, and arms carried by said levers adapted to be brought into engagement with said teeth to arrest rotary movement of said casing.

5. In a device of the class described, a casing, a peripheral deck for said casing journaled thereto at each end, transverse straps surrounding the casing and connected to the deck, and means carried by the deck adapted to be brought into engagement with said casing for arresting movement thereof.

In testimony whereof I afiix my signature in presence of two witnesses.
